Used by biologists to culture bacteria and other microbes, these plastic petri dishes provide the perfect home for "growing" your latest science experiment. Nurture a new bacteria for this year's science fair project, and follow in the steps of Dr. Alexander Fleming when he discovered Penicillin in 1929! Recommended for children ages 6 and up.

How Does It Work?
Partially fill your Petri dishes with a perfect mixture of nutrients that provide food for microbe growth. Scientists often use hot agar mixed with salts, amino acids and other substances perfect for supporting the particular microbes they wish to study. When the mixture cools, place your tiny cells on top of the surface and watch them multiply. Don’t worry, they take some time to grow!

- perfect for home or school Review by kathy wilmovsky
These petri dishes are perfect for showing either your own kids or a class full of students all the germs that are on commonly used items. They are a great size and the kids are amazed at how disgusting some things are to touch. When we added hand sanitizer to the center of some of the dishes, it really made a difference and inhibited the growth of the bateria. This was a great example as to why kids should clean and sanitize their hands! (Posted on 5/31/13)

- Petri Dishes Review by Sheri
We ordered the Petri dish kit for my 5th grader's science project, Who Would You Rather Kiss, Your Mom or Your Dog?. It worked very well and was easy to use. We will definitely order something from your website next year.(Posted on 5/31/13)
- Great for Science themed parties! Review by Paula
I used these petri dishes to make "gummy brains and worms" for my sons science themed birthday party! I used green jello and gummy worms and bugs! The kids loved them! (Posted on 5/31/13)
- Fun to fill with jello Review by Melissa Malone
I ordered these for my daughter's science themed birthday party and filled them with green jello. They looked just like the agar you would use in a biology lab. We also used them for the milk, food coloring, and soap experiement which the kids thought was super cool. (Posted on 5/31/13)
